Since when has the mangalsutra become so important for Bani? She has never been wearing it after she came back to WM after the first leap and DDG drama. She was not wearing it when JW threw her out of the house. After that he burned all her belongings. Where did she get her mangalsutra from? Why all this now when she did not respect it by wearing it when she was married to JW and living with him?
So if mangalsutra breaking has symbolism then not wearing mangalsutra while married should also have some symbolism right? It should work both ways. Bani also did pooja's and went to the temple without wearing a mangalsutra. So was God angry at her for doing that and so separated her from her husband? Please let us not bring God into it. The creatives can mess with God - I don't want to.
Suwas - society sees a couple - a husband wife together - people cannot go into other peoples's minds to see who he is with mentally. Also, Bani's husband thinks about her with bitterness and hatred not with love.
